Abstract

Abstract Two new species of J urassic C hrysopidae are described: M esypochrysa sinica sp. nov. ( L imaiinae) from the M iddle– U pper J urassic boundary interval of D aohugou ( C hina) and B aisochrysa pumila sp. nov. ( L imaiinae) from the U pper J urassic of K aratau ( K azakhstan). M esypochrysa intermedia P anfilov, 1980, previously known from K aratau, is recorded from D aohugou. M esypochrysa sinica sp. nov. and M . cf. intermedia from D aohugou are considered to be the earliest known, unquestionable green lacewings. L embochrysa R en and G uo, 1996 is synonymized with M esypochrysa M artynov, 1927. M esypochrysa makarkini N el et al ., 2005 is synonymized with M . intermedia , and the size range of their forewings is discussed. Male and female terminalia of the M esozoic green lacewings are described for the first time. The diversification of ants is considered a possible cause of the extinction of L imaiinae during the early E ocene.
